252814 ÷ 79 
The aim is to understand the frequency of 79 in 252814.

Going ahead to step 1:
2 divided by 79 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 79

Advancing to step 2:
If we divide 25 by 79, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 79

Moving on to step 3:
The number 79 fits into 252 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 237 from 252 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 79

Going ahead to step 4:
The number 79 fits into 158 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we take 158 away from 158, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 79

Going ahead to step 5:
If we divide 1 by 79, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 320.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 79

Advancing to step 6:
When dividing 14 by 79, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 3200.0
Subtracting 0 from 14 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 79, we get 1 and a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 3200.1
Subtracting 79 from 140 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 8:
If we divide 610 by 79, we get 7 and a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 3200.17
Subtracting 553 from 610 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
79 can be fit into 570 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 3200.177
Deduct 553 from 570 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 3200.177, with a leftover of 0.0017.
